Attributes:
Size
These face shields should be able to fit just about anyone. The material of the forehead bands are sturdy, but flexible enough for the user to wrap around the top of the forehead. The designs have an extra component to them that helps with not only padding for the forehead, but allows it to protrude from the face as well, making it adequate for all types of faces, even users with glasses. Since this personal protective device is meant to be used as an add-on to the mandated face masks, there is no need for the shield to closely conform to the face, just as long as the shield provides a barrier for the entire face length.
Air Flow
Since this device is a face shield rather than a face mask, it is designed to have an appropriate amount of space for both breathing and protection against the virus. The frame should be able to help minimize any droplets or aerosols from reaching the facial area. The frame itself is mean to protrude from the face in order to accommodate to one’s facial features, this leaves a reasonably sized opening at the bottom of the shield. This opening will allow enough airflow for one to breathe in and out.
Durability
In general, these masks are meant for a one time use, or to be disposable in order to minimize the risk of contamination. However, the shields should be durable enough to be used more than once as long as the user disinfects it often.
How to Use:
It’s as simple as placing the band across the top of one’s forehead, making sure the frame completely covers the face. Use the elastic band located on the back of the head to securely fasten the shield to the face to prevent it from moving or slipping.
Which shield is best suited for my needs?
In response to the pandemic, three kinds of masks were deployed within the project. These were laser cut shields, injection mold shields, and 3D printed shields. Each shield has its own design and can be better suited for different cases. (Range is based off the most convenient price for each type and amount of materials for the shields.)
- For 1-100 shield frames: one should go for the 3D printed shields
- For 100- 1000 shield frames: one should go with laser cut shields
- For 1000+ shield frames: one should go for injection molded shields
In terms of screens:
- 1-1000: one can die cut each and every one with a team
- 1000+: die cut is recommended to meet the need for larger amounts
